Synopsis
Phantoms for pre-clinical systems have not been standardized, and none in the literature permit the wide variety of measurements possible with the ACR phantoms. We present a low-cost, open-source, modular phantom made of 3D-printed and off-the-shelf parts that mimics the functionality of the ACR phantoms on an appropriate scale. Standard, inexpensive manufacturing techniques are sufficient to create the fine features required at this scale. Configuration of the phantom can be customized to suit each site’s needs. Possible measurements include image uniformity, distortion and SNR; slice location, thickness, and angle; radial, linear, and low-contrast resolution.
